Abstract
An electronically controlled actuator for controlling a turbocharger has a motor, a speed change mechanism and a position sensor contained in a case consisting of a body and a cover. The driving force of the motor is transmitted through the speed change mechanism to an output shaft to drive the movable vanes of a turbocharger for turning. A first bearing supporting the output shaft for rotation is held on the cover, and a second bearing supporting the output shaft for rotation is held on the body. The position sensor is mounted on the output shaft of the motor. The reliability of the actuator is improved.
